How to get a reference on a view instance in ember / emberjs from static javascript?

Question

I have seen a lot of questions about that on the web (SOF and Google) but so far no clear answer to the issue.

I have a usual Ember application with various views

Answer 1

Ember already has a "Global views hash"

search ember.js for Ember.View.views = {}

It is indexed by every views' element id, so getting a view is as easy as:

myView = Ember.View.views[$('.myViewSelector').attr('id')]

My mentor however believes using this method is a dirty hack and advised me to find a better way. He had written a test helper:

window.lookupView = function(key) {
  var activeViews = app.__container__.lookup('router:main')._activeViews;
  if(!activeViews) { throw new Error("No active views."); }
  if(!activeViews[key]) { throw new Error("No view '%@'.".fmt(key)); }
  return activeViews[key][0];
};

which I used to get my desired parentView and then any children with parentView.get('childViews')
